•Satan, like Prometheus, gave knowledge to humanity by giving Eve the fruit from the forbidden tree. Because of Satan, humanity gained knowledge of good and evil, according to Genesis. Since we couldn't have possessed knowledge of good and evil before eating the fruit, Adam and Eve couldn't have known that eating the fruit was evil, so it seems a little harsh to punish them as severely as God did. Satan gave humans true capacity for moral judgment, unlike God, who simply expected everyone to mindlessly obey his orders.
•There is no biblical record of Satan engaging in the murder of torture of any human being, unlike God, who is guilty (and proudly guilty) of commiting genocide.
•There is no biblical record of Satan ever ordering someone to kill someone else, unlike God, who has repeatedly demanded the deaths of those who commit even the smallest of offenses.
•Satan will not be holding a massively dramatic ceremony full of blood and death for the return of his son to Earth. God apparently will.
Satan's real name is Samael,
he is "the great prince in heaven." (Pirḳe R. El. xiii., beginning), who rules over angels and powers (ib.; Martyrdom of Isaiah, ii. 2). (Tan. on Gen. xxxii. 35; Jellinek, l.c. vi. 31, 109, etc.). He flies through the air like a bird (Targ. to Job xxviii. 7), and, while the ḥayyot and ofannim have only six wings, he has twelve. In so far as he is identified with the serpent ("J. Q. R." vi. 12), with carnal desire (Yeẓer ha-Ra'), and with the angel of death, all legends associated with Satan refer equally to him.Even at the creation of the world he was Lucifer.
heaven to seduce the first human pair (Pirḳe R. El. xiii., beginning; Yalḳ. Gen. i. 25), and for this purpose he planted the vine, the forbidden tree of paradise (Greek Apocalypse of Baruch, iv.). He was himself the serpent, whose form he merely assumed (ib. ix.; "J. Q. R." vi. 328), and was one of the leaders of the angels who married the daughters of men (Gen. vi. 1-4), wrestled with Jacob.Samael is represented as the angel of death ("Revue de Numismatique," 1892, pp. 246, 251). Eve is supposed to have become pregnant by him. Giving birth to Cain, the first Human being.
This angel Samael is said to be related with the planet Mars, and he states that explicitly in the Zohar. Samael says:
“...my entire domination is based on killing. And if I accept the Torah, there will no longer be wars. My rule is over the planet Maadim (Mars) that indicates spilling of blood.” - ספר הזהר Zohar
Ares, Mars, Samael is the same force. He wages his war on behalf of God, not for selfish purposes, and not to punish indiscriminately, but to punish on behalf of God, with the permission of God, and for the good of all. Samael performs the will of God. This the power of Samael: to kill and to make alive. That power acts in accordance with the Most High, those causes which exist above the sephirah Geburah. Geburah (severity) is the sephirah of Mars from which the angel Samael departs in order to punish those who deserve it and to reward those who deserve it. This is simple cause and effect. This is in the the root of Judaism and Christianity, but everyone ignores it. (http://samaelaunweor.info/identity/38-the-angel-samael.html).
